Large plot studies were conducted on typical grower farms, with root-knot nematode, reniform nematode or no nematodes to evaluate the impact of Temik sidedress applications over a three-year period. Results indicated a significant yield increase in 1998 and 1999 for sidedressed plots compared to the untreated plots even in the absence of nematodes on some fields. However, in 2000 there was only one location with a significant yield increase attributed to sidedress applications.
